       10. The connector according to  claim 8 , wherein the protrusion piece is press-fitted and held in the header fitting body. 
     
     
       11. The connector according to  claim 10 , wherein the protrusion piece is press-fitted from the side opposite to the side of the header fitting body fitted to the socket fitting body. 
     
     
       12. The connector according to  claim 10 , further comprising a plurality of protrusion pieces, wherein the protrusion pieces are press-fitted in the both ends of the header fitting body in the longitudinal direction. 
     
     
       13. The connector according to  claim 8 , wherein two of the plurality of protrusion pieces are connected by a bridging portion. 
     
     
       14. The connector according to  claim 13 , wherein the bridging portion includes a recess that is formed on the opposite side to a side fitted to the socket fitting body of the header fitting body with the protrusion pieces held by the header fitting body. 
     
     
       15. The connector according to  claim 1 , wherein a recessed portion and a protruded portion are, respectively, formed inside the sidewall surface on the inner side in the socket fitting body and inside the sidewall surface on the outer side in the header fitting body, the recessed portion and protruded portion being fitted to each other. 
     
     
       16. A header used in a connector, the connector, comprising:
